Preprocessor definitions

#define VORTFLOW_H

#define VORTFLOW_HELP "Velocity-vorticity Navier-Stokes is really cool, see the vortflow.c\ndocumentation for a complete description. To use it, add option:\n -with-vortflow\nand control it with properties and body force parameters:\n -viscosity <eta> viscosity [1.0]\n -density <rho> density [1.0]\n -sineforcet0 <Ft0> Sinusoidal force onset time [2.0]\n -sineforcemax <Fmax> Sinusoidal force amplitude [1.0]\nIf -symmetry_x and -symmetry_y are specified, then one may also specify\ninitial and boundary conditions describing stagnation flow using:\n -stagnation_flow <umax> Maximum stagnation velocity [1.0]\n\n"
